I wore this as part of my Star Trek TOS cosplay for Planet Comicon's Star Trek themed group photo shoot. It's a decent uniform shirt for the price but it should be noted that the insignia is too small and the stitching in various places was not good quality. Overall, it fit well and was very comfortable. If you want authenticate, go for the ANOVOS $200 version.

It's a bad material, very tight not much breathing room. I recommend getting a size or two bigger, I would prefer if this was more of a cotton then this athletic material. Also the sleeve ranks are a cheap gold ribbon looks nothing like the show which is sad. Still nice for costumes.
